CeCd3As3 crystallizes into a hexagonal ScAl3C3-type structure. The magnetic Ce-ions form the triangular lattice of the two dimensional layer. Thermodynamic and transport properties of CeCd3As3 were investigated by measuring the magnetization, electrical resistivity, and specific heat. The Ce-ions in this metallic compound are well localized but do not order down to 0.42 K despite having a large negative Weiss temperature. In this presentation, anomalous physical properties due to the geometrical frustration of Ce-ions will be discussed.
